    Abstract: A bone plate includes at least one hole extending through the bone plate from an upper plate surface to a lower plate surface along a central hole axis that is oriented along an axial direction. The at least one hole defined by an interior surface of the bone plate. The interior surface further defining a plurality of columns sequentially located about a circumference of the interior surface and a plurality of recesses located circumferentially between the columns. Each of the columns defines a plurality of thread segments each defining a root, a first thread surface extending from the root to a first crest, and a second thread surface extending from the root to a second crest. At least a portion of the first and second thread surfaces are offset from one another at a thread angle. The thread angle of at least one of the thread segments is in a range of about 5 degrees to about 59 degrees.

    Abstract: 본 발명은, 나사 반잠김식 뼈 고정 장치에 관한 것으로서, 보다 상세하게는, 외경을 따라 나사산이 형성된 몸체부와, 하면이 하향 만곡진 머리부로 구성된 뼈 나사 및 머리부의 하면 일부분이 안착되는 하향 만곡진 안착면과, 안착면 중앙에 형성된 관통홀로 이루어진 적어도 하나 이상의 반잠김 홀을 구비한 뼈 플레이트를 포함하며, 뼈 플레이트의 반잠김 홀 상단의 내경이 뼈 나사의 머리부 상단의 외경 보다 더 작으며, 머리부의 하면에는, 하향 수직으로 제1 나사부가 형성되고, 반잠김 홀의 안착면에는, 제1 나사부에 대응하는 상향 수직의 제2 나사부가 형성되어 제1 나사부와 제2 나사부가 서로 수직방향으로 결합되는 것을 특징으로 하는 나사 반잠김식 뼈 고정 장치에 관한 것이다. 본 발명에 따르면, 뼈 나사의 머리부의 하면이 뼈 플레이트의 반잠김 홀에 수직방향의 결합력은 없으면서 수평방향의 결합력만 작용할 수 있도록 반잠김 나사결합됨으로써, 연부조직이 적은 부위의 골절치료시, 뼈 모양에 맞게 휨 가공이 용이한 얇은 뼈 플레이트를 사용할 수 있고, 추후 골유합이 다되어 뼈 나사를 역회전시켜 뽑을 때, 뼈 나사를 보다 쉽게 뽑아낼수 있다.

    Abstract: The invention concerns a bone plate system comprising: a bone fastening element (5) comprising a shaft with a first thread with a first lead length, the fastening element further comprising a head with a second thread on its outer surface, the second thread having a second lead length, the outer surface having a first hardness; and a bone plate (3) with a second hardness which is smaller than the first hardness, the bone plate (3) comprising a non-threaded through hole (11) in a non-assembled state for receiving the bone fastening element (5), the hole (11) comprising a first hole portion with a first three-dimensional shape and a second hole portion with a second, different three-dimensional shape. The first lead length substantially equals the second lead length, and the second thread is arranged to irreversible deform the wall of the hole to form a female thread on the wall.

    Abstract: Implant positioning devices for use with and assisting in positioning orthopaedic fixation devices (such as bone plates, etc.). An implant positioning device may include a body that has a fastener guide with slits in a first end of the fastener guide that form a retaining arm proximal to the first end of the fastener guide. The implant positioning device may also be coupled to a bone plate by a retaining beam positioned within the implant positioning device to facilitate ease of alignment and insertion of the fastener into a fastener apertures of the bone plate.

    Abstract: A targeting device (100) for use in fixation of bone fragments at a bone fracture. The targeting device comprises an elongated body portion (110) comprising a first body end (111), an opposed second body end (112), and body through holes (113a, 113b,113c) extending from the first body end to the second body end for guiding a respective fixation means (303; 303a, 303b, 303c) through the body portion. In its second body end the body portion is configured with a snap-fitting means (114) configured to removably attach a fixation plate (150) to the body portion such that fixation through holes (151) of the plate are located in line with a respective body through hole and, when in use, to provide a surface of the plate to abut a surface of an outer bone fragment for subsequent fixation of the plate to the fragment. The targeting device comprises further a bracket (120).

    Abstract: An implant for a human rib can include an elongate body, a plurality of bores, and a placement tool interface. The elongate body can include a first portion including a flat outer face where the elongate body can be curved along a plane perpendicular to the flat outer face. The second portion can extend from the first portion to form a curved outer face. The plurality of bores can extend through the flat outer face of the first portion and into the second portion. The bores can extend partially into the curved outer face of the second portion. The placement tool interface can extend into the body.
